You can get an external 1TB hard drive for NZD 60 if you shop around. That's USD 37 or GBP 29. How much data do you have and how valuable? You don't need a whole 'nother laptop to backup! If you did, you could get a 2nd-hand laptop adequate for the purpose for NZD 150 (USD 92, GBP 72). Again, how much data do you have and how valuable? A new 64 GB memory stick is just NZD 8 (I'll let you do your own currency conversion).
R works very well with data held outside R in formats that are not R-specific. I would expect (the master copies of) your documents and data to be held outside the directory where R is installed and in formats (like .csv) that are the same no matter which version of R you use to read them, so it's not clear why upgrading R should put your documents and data at risk. In any case: - which files should be backed up? All of them. - when is the right time to back them up? Now. - what should it cost me to take backups? A lot less than losing your data. And even if you buy another 2nd-hand laptop to do it, less than a day's pay. On Wed, 19 Jun 2024 at 20:08, Ogbos Okike <giftedlife2...@gmail.com> wrote: > > Dear Martin, > I agree with you.
